METHOD OF. FORMING TIE-PLATES.

7 Specification of Letters Patent.

Patented Jan. 3, 1911.

Original application filed June 18, 1908, Serial No. 439,159. Divided and this application filed August 23,

, 1909. Serial No. 514,082.

To all whom it may concern:

Be it known that I, \VILLIAM L. DE RnMnR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Method ofForming' Tie-Plates,

of which the following is a specification.

My invention relates to the forming of tieplates and the'object thereof is to provide a simple and efficient method of producing plates of this character. I

Speaking in general terms, my method as practiced by me consists in first forming a long blank or bar containing a considerable number of tie-plates in succession and of peculiar formation and then severing said blank transversel at proper points in order to produce accurate tie-plates.

I do not herein claim the tie-plates or the general method or process of forming the blank or bar as the same constitute the subject matter of an original application filed on June 18, 1908, Serial No. 439,159, of which the within application is a division,

and of a second divisional application filed simultaneously herewith on August 23, 1909,.

tie-plates; and Fig. 6 a perspective thereof.

In practice the blank 'orbar is formed by the rolling process into a plurality of tie plates which is subsequently severed into tie-plate lengths and I will therefore hereinafter refer, without intention of limitation, to the formation ofsaid blank or strip of such rolling process in order that my invention may be readily understood.

In practice a billet or piece of metal 1s reduced by suitable rolls to plate form as shown at a and is passed through; a pair of finishing rolls such as shown in Figs. 1 and 2. The upper roll band lower roll 0 are rotatably mounted in suitable .bearings d in a supporting frame. e, and the lower roll is provided with annular eripheral grooves f for formin or rather ishingthe bottom flanges g o the tie-plates when such flan es are to be used. The upper roll is provided with longitudinal slots or grooves h for forming the transverse shoulders or ribs 2' which engage oneside of the rail flange and which by prefrence, though not of necessity, extend all the way across the plate.

In' addition the upper roll is provided with I recesses h preferably two in number and adjacent the slots h and in communication therewith, with the result that in the rolling of the blank in this particular instance projections which are here in the form of bosses or reinforcements k and -Z are formed integral with such shoulders and at an angle thereto. The blank or strip after bein thus rolled into the form above describe and thereby consisting of a plurality of tie-plates joined together, is now severed in suitablemanner transversely atpoints intermediate the ends of the bosses so formed and as determined by theposition of. the shoulders, as indicated by the dotted transverse lines a. in Fig. 3. By preference and according to practice, the blank or bar is properly perforated or punched in order to provide the spike holes a before said severing into tieplate lengths. One of the resulting tieplates is' indicated in Figs. 5 and 6 from which it will be seen that the act of severing the blankor strip in the manner'described results individing the bosses ofsuch blank in two, the portions 7.: constituting the bosses for the shouldered end ofone plate and the portionsZ constituting the bosses for the nonshoilldered end of the next adjacent plate.

My method or process of forming tieplates results in a superior and eflicient product, thetie-plates being particularly accu rate and undistorted so as to perfectly fit the rail and moreover, being uniform in size.

I claim: v I 1. The process of making tie-plates having a body portion provided on one face with PI'OJGCtlOIlS- at opposite ends thereof, which consists in forming said projections on a blank and severing the blank throu h the cent thereto on a blank and severing' the rejections intermediate their ends; su stanblank through the bosses intermediate their 10 tially as described. ends; substantially as described. 2. The process of making tie-p1ates hav- 5 ing a body portion provided on one face with WILLIAM DE REMER' a transverse shoulder and bosses at the oppo- WVitnesses: site ends of said body portion which consists S.
